Apparatus And Method For Configuring Radio Connection In Multiple Component Carrier System

Abstract

A method of a Mobile Station (MS) configuring radio connection in a multiple component carrier system is provided. The method includes receiving distribution information from a Base Station (BS) through a first Component Carrier (CC), selecting a second CC for radio connection to the BS on a basis of the distribution information, and performing the radio connection through the second CC.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority of U.S. Provisional Application No. 61 / 230,995 filed on Aug. 3, 2009 and Korean Patent Application No. 10-2010-0067268 filed on Jul. 13, 2010, which are incorporated by reference in their entirety herein.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to wireless communication and, more particularly, to an apparatus and method for configuring radio connection in a multiple component carrier system.[0004]2. Related Art[0005]Wireless communication systems are widely deployed in order to provide various kinds of communication services, such as voice and data. In general, the wireless communication systems are multiple access systems which can share available system resources (e.g., bandwidths and transmission power) and support communication with multiple users. The multiple access systems can include, for example, a Code Division Multiple Access (CDMA) system, a Fr...

AI Technical Summary

Benefits of technology

[0014]In a plurality component carrier system, an MS selects a component carrier based on a distribution information provided by a certain carrier (or a cell), and transmits an RRC connection request message through the selected component carrier. Therefore, an overhead problem, which RRC connection request messages are concentrated on a specific carrier, can be solved.

Problems solved by technology

However, it is not easy to allocate a large frequency bandwidth except some regions in the world.

In a multiple component carrier system, however, whether an RRC connection request message will be sent through which component carrier has not yet been determined.

Further, in the case in which a plurality of user equipments perform an RRC connection request through only a specific component carrier having a good channel state, overhead can occur because of excessive uplink transmission through the specific component carrier.
